Front mech will need to be dropped lower to stay within 1-3mm from the largest chain ring.
Rear mech can handle a 2tooth difference between 11-34 and 11-32.
OK, thanks for the tips. I'll make sure to watch the chain length. I'm thinking I might take the current chain on my bike and move it to the trainer. That way I'm running a new chain with the new chainrings.
Appreciate it.
